If you say that you’re “nuking” something, pretty much everyone will know that you mean you’re heating something in the microwave. It’s technically incorrect, of course, as the magnetron inside the ...

A fungus that evolved at Chernobyl and is now grown on the ISS, Cladosporium sphaerospermum, slightly reduced radiation levels.

Recent advances in radiation dosimetry have significantly refined the precision of radiotherapy treatments, particularly as clinical systems increasingly integrate magnetic resonance imaging. The ...
